HOW FUSION WORKS

A different approach to adhesive rheology

 

Fusion™ is a patented two-component liquid system developed for starch- and flour-based corrugating adhesives.

After activation in the alkaline adhesive environment, Fusion forms a controlled network within the formulation. This network provides viscosity and suspension with reduced dependence on the traditional pre-cooked starch carrier.

 

Controlled behaviour under shear

During glue application, the adhesive is exposed to high shear between the glue and doctor rolls. Fusion supports shear-thinning behaviour, allowing the adhesive to flow smoothly and form a controlled glue film.

When shear decreases at the flute tip, viscosity rapidly recovers, helping the adhesive remain where it is required for controlled penetration and bonding.

 

What Fusion can enable

Reduced carrier requirement
Allows the plant to evaluate substantial reduction or replacement of the traditional pre-cooked carrier portion.

Native starch formulations
Designed to work with native, unmodified starches.

Stable viscosity
Supports consistent rheology during production and after extended standstill.

Lower glue-film settings
Can support controlled application at reduced mechanical glue settings.

Simpler glue preparation
Reducing or eliminating the pre-cooked carrier can simplify the preparation sequence.

Lower gelling temperature
Formulation parameters can be optimised to support lower starch gelatinisation temperatures where production conditions permit.

 

Validated on your corrugator

Every corrugator, paper programme and adhesive system is different.

For this reason, Fusion is evaluated against the plant's existing formulation under controlled production conditions.

A Fusion industrial trial can measure:

• adhesive consumption

• starch consumption

• viscosity and stability

• gelling temperature

• glue-film settings

• machine performance

• bonding and board-quality parameters
